22 lut 2021 · Phobos and Deimos are the remains of a larger Martian moon that was disrupted between 1 and 2.7 billion years ago, say researchers from the Institute of Geophysics at ETH Zurich and the Physics Institute at the University of Zurich.
1 mar 2021 · Close up, Phobos and Deimos resemble tiny misshapen captured asteroids… but how did they get into the neat, tidy orbits that we see today? Phobos (the large moon) and Deimos captured together...
29 lis 2021 · Imaging data reveals a low albedo of both moons – Phobos: ∼0.07; Deimos: ∼0.08. Also, Phobos manifests distinct redder and bluer units, whereas the surface of Deimos is globally comparable to the Phobos redder units with localized streaks of brighter material.
22 lut 2021 · For Phobos, \({{\Delta }}{e}_{2:1}^{{\rm{Mars}}}=0.032\), \({{\Delta }}{e}_{3:1}^{{\rm{Mars}}}=0.002\) and \({{\Delta }}{e}_{1:1}^{{\rm{Sun}}}=0.0085\), whereas for Deimos, \({{\Delta...
8 gru 2017 · Phobos and Deimos bear more resemblance to asteroids than to Earth's moon. Both are tiny — the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only...
Compared to the Earth 's Moon, the moons Phobos and Deimos are small. Phobos has a diameter of 22.2 km (13.8 mi) and a mass of 1.08 × 10 16 kg, while Deimos measures 12.6 km (7.8 mi) across, with a mass of 1.5 × 10 15 kg.
18 kwi 2018 · The lower end of the basin-forming impactor size/energy estimates is consistent with Phobos-Deimos originating from the Borealis event, with subsequent Utopia and Hellas impacts producing less massive and more compact disks that did not yield long-lived moons.
